Rekkeviddekontroller
Rekkeviddekontroller—literally "range controllers"—are a class of instrumentation used primarily in process automation and industrial control systems. The devices monitor and regulate the operating range of process variables such as temperature, pressure, flow, or chemical concentration. By defining upper and lower limits, a rekkeviddekontroller ensures safe and efficient system performance, automatically adjusting actuators or triggering alarms when variables approach the predefined boundaries.
The core principles of a rekkeviddekontroller are straightforward. A sensor feeds real‑time data to the controller,
Rekkeviddekontroller are commonly deployed in chemical manufacturing, oil and gas, water treatment, and HVAC systems. In
Historically, range control evolved from basic mechanical thermostats to sophisticated digital controllers with advanced diagnostic features.
